S AKJxxx H Ax D Axxx C x IMP pairs A nice hand, partner deals and passes, RHO 1D I double, LHO 1H, partner passes, RHO rebids 2D, I bid 2S, which is passed out. Upon seeing declarer's hand, my "expert" partner leaves without a word. Dummy comes down with: S Qxx H Kxxx D xx C Jxxx Making 5, of course. With my partner passing, LHO still unlimited, and the opponents not finding a fit, I think I'm promising a very strong hand (about 18-21 points) needing only a few cards from partner to make a game. Does my partner have any reason to be upset?
